MAX690RCSA+T is a voltage supervisor designed by MAXIM Integrated primarily for applications such as microprocessors, coprocessors, and other general purpose ICs. This IC provides accurate monitoring of supply and reset voltages, independent or simultaneous reset control, integrated voltage clamps, and adjustable reset timing. It also features an internal circuit that allows programs to reset without power cycling the device. This supervisor can be used to monitor voltage levels, detect a brownout condition, and generate a reset signal to detect faults or errors on the IC.

The MAX690RCSA+T is powered by the VCC pin and is capable of handling up to 6V. The device includes three active low output pins: RESET, RESET, and RESET. The RESET pin is used to monitor the power supply voltage and reset the system when the voltage falls below the preset threshold level. The RESET pin is used to generate a reset when the voltage falls below the threshold, and the RESET pin is used to enable or disable the RESET pin. The voltage regulators of the MAX690RCSA+T can be configured to provide a Reset Delay feature, which extends the reset pulse by a user-configurable amount of time, allowing the microcontroller or processor to operate in a normal state until the voltage level stabilizes which prevents false resetting.

The device contains an integrated voltage clamp circuit which can be enabled or disabled depending on user requirements. When enabled, the voltage clamp circuit prevents excessive voltage levels on the RESET, RESET, and RESET pins, thereby protecting the system from excessive voltage levels. The integrated voltage-clamping circuit also helps to reduce the need for external components.

The MAX690RCSA+T also includes an adjustable reset timing fit, which allows the reset to remain active for a predetermined amount of time, ensuring that the microcontroller or processor receives an adequate reset duration. The reset timing feature on the MAX690RCSA+T can be configured to be in sync with the system clock, allowing for precise reset timing for the application. Additionally, the reset timing can be programmed as short as 0.25 microseconds, allowing for very fast resetting.

The MAX690RCSA+T also contains several internal protection circuits which prevent it from being damaged from high temperature, over-voltage, or inrush current. The device contains a metal-oxide-semiconductor field-effect-transistor (MOSFET) that limits the inrush current supplied to the device, allowing the supervisor to protect itself against a high-voltage supply.

The MAX690RCSA+T is an excellent solution for reset, monitoring, and protection tasks in many applications, particularly those involving microprocessors and other sensitive ICs. This voltage supervisor provides accurate monitoring of supply and reset voltages, independent or simultaneous reset control, integrated voltage clamps, and adjustable reset timing. In addition, the device features a variety of protection circuits that help ensure the device is not damaged by over-voltage, over-temperature, or inrush current. As a result, the MAX690RCSA+T is an ideal choice for a wide range of applications.
